The effective diffusion coefficient and rate constant of intraparticle transport were calculated. 求出了颗粒内有效扩散系数和颗粒内扩散速率常数。
The knowledge of diffusion is crucial in many processes because reactions and separations are often limited by a diffusional process. 摘要许多过程都涉及扩散控制的传质,相应的扩散速率计算对过程工程的精确量化具有重要意义。
In some sense, it is the synchrony that induces diffusion slowing. 这种同步状态正是扩散速度下降的原因。
Nevertheless, temperature has a very significant effect on the rate of diffusion. 但是温度对扩散速度却有非常大的影响。
